The mini getaway comes after a trying few weeks for the young couple.

Although he has already taken one paternity test, her lawyers are requesting that he take another.

According to the NY Daily News, Yeater’s lawyer, Jeffery Leving, is requesting that the singer take another test while she is present.

He told the site: ‘I want a new DNA test with both sides together at a lab in California as soon as possible. soon as I tell her to do it, she’ll do it. We need proper protocol and a chain of custody.’

It has also been reported that he is speaking with Bieber’s lawyer Howard Weitzman.

Weitzman repeatedly has refused to comment on the claims.

A spokesperson for Justin told MailOnline: 'Justin has taken the test. There is currently no case pending against him and there's been zero evidence supporting this claim.'

Bieber also confirmed that he had taken the test while appearing on The Late Show.

He told host David Letterman that he could 'smell a weasel' about the allegations.

'It's pretty crazy [that] people make up false accusations,' said the Baby singer.

'It's going to happen. Being in the spotlight, people can say whatever.
